Why Slider Self-moving of Hydraulic Press MachineUpdate：2024-06-04 Hits：136
The slider of hydraulic press machine is one of the important components, which can bear the weight and working load of the fuselage, and provide preloading and forming force. In the working process of the hydraulic press machine, when the working medium of the hydraulic cylinder is compressed and converted into hydraulic energy, the hydraulic energy needs to be transmitted to the hydraulic press slider through the piston of the hydraulic cylinder. The hydraulic press slide moves downward under pressure, which provides the necessary pressure to form the workpiece.However, in the process of daily use, the hydraulic press machine will inevitably have various failures due to long-term work, and the slider self-moving fault is a more common one. When this happens, it not only leads to a decrease in productivity, but can also affect equipment life and safety.
Reasons for the slider slide of hydraulic press machine
1. Oil circuit failure
Oil circuit failure is one of the most common causes of hydraulic press slide slides. A faulty oil circuit can cause the pressure in the cylinder to be unmaintainable, causing the slider to slip. The cause of oil circuit failure may be oil leakage in the oil connection pipe, poor spool control, or improper operation of the hydraulic pump. In this case, it is necessary to find the fault point for repair or replacement.
2. The seal of the hydraulic cylinder is damaged
Worn or damaged hydraulic cylinder seals are also one of the causes of hydraulic press slides. If the seals of the hydraulic cylinder are worn or damaged, it will cause air pressure to leak and the pressure inside the cylinder will be unstable. This will cause the slider of the hydraulic press to slide, and even the slide will be unstable in serious cases. It is necessary to detect the sealing condition of the hydraulic cylinder in time and replace it.
3. The pressure of the hydraulic system is insufficient
The slide of the hydraulic press can also be caused by insufficient pressure in the hydraulic system. Insufficient pressure in the hydraulic system can be due to a damage to the hydraulic pump, insufficient working capacity of the pump, or a leak in the hydraulic system causing a pressure drop. It is necessary to find the cause and repair it in time.
How to maintance the slider self-moving of hydraulic press machine
Here are some ways to deal with the slider slide problem based on the causes.
● Check the hydraulic system: check the various components of the hydraulic system such as the hydraulic pump, needle valve, and hydraulic control unit, and find out the parts that are not working properly or aging for replacement.
● Replace the seals: Replace the seals of the hydraulic cylinders or cylinders with poor sealing to ensure that the oil will not leak.
● Adjust the hydraulic valve: adjust the spring tension of the hydraulic valve to solve the problem that the oil cannot flow into the hydraulic cylinder or excessively flow into the hydraulic cylinder, and ensure that the slider runs normally.
There are many reasons for the slider of the hydraulic press machine, and it is necessary to find the accurate cause through careful inspection and troubleshooting, and understanding the reasons for the automatic decline of the hydraulic press and the corresponding solutions can help us better maintain the stable operation of the hydraulic press and its hydraulic system, and improve work efficiency and safety.
